🐛 Bug Fixes

🔧 Performance Improvements

• perf(extensions): load store summaries and installed extensions in parallel, check updates in the background, and cache list/detail requests @monkeyWie (#1583)
• perf(http): use 64 KiB connection read buffers to reduce HTTP download CPU overhead @Arpit-Khandelwal (#1588)
• perf(http): replace per-read goroutines with a reusable timeout timer and prevent timed-out reads from writing into reused buffers @Arpit-Khandelwal (#1597)

🧰 Maintenance

• refactor(ios): simplify continued processing startup and share task-event decoding with Live Activities @UltraGeek0102 (#1547)
• refactor(downloader): make resource resolution request-only; download options must now be supplied when creating tasks @monkeyWie (#1595)

🧪 Tests

• test(bt): isolate shared-piece cleanup fixtures from automatic part-file promotion to stabilize regression tests @monkeyWie (#1531)

🚀 CI/CD

• fix(ci): restore Windows ARM builds with scoped MSVC compatibility settings @monkeyWie (#1586)
